ok,
sit her down tell her about sex, (dont do birds and bees, that was for the kids who were born before the 80's)
tell it to her straight tell her about stds, not just aids.
tell her that you cant tell with all of them and that they dont show up right away.
talk to her about birth controll, find out what types your doctor is willing to put her on, and then discuss with her what type she would like to try. make her feel like she can come to you with questions. be serious with her treat her like an adult by how you talk to her. remind her that accidents do happen but you would prefer her not to have sex and make you a grandma just yet.
to tell a teenager these days to just say "NO" dosent work. i was a teenager not too long ago and remember very well.
if you arm your child with information, she has the power to use it and judge for herself. if she has nothing well you will be a grandmother sooner than later.
just because she is taking the pill dosent meen she is a bad girl just a girl who is trying to protect herself from certain situations.
also tell her to keep the fact that she is on any kind of birth controll to herslef, some other parents might not like it and some kids may cause her problems with it.
this may sound silly but teach her about condoms as well. how to use them and what to do.
dont ask her for the nitty gritty information just tell her that you were a kid once,
My mother did not have this kind of talk with me, but i had a very good adult friend who did and i was able to make better decisions for it. just tell her to talk and that you wont ever be angry a little upset maybe bbut never angry.
this ofcourse is just my opinion i have one little boy and a girl on the way, with what is out there today this is my plan of action.
